add_cv Class
The latest version of this topic can be found at add_cv Class.
Makes const/volatile type from type.
Syntax
template <class Ty>
struct add_cv;
template <class T>using add_cv_t = typename add_cv<T>::type;
Parameters
Ty
The type to modify.
Remarks
An instance of the type modifier holds the modified-type add_volatile Class< add_const Class<Ty> >.
Example
#include <type_traits>
#include <iostream>
int main()
{
std::add_cv_t<int> *p = (const volatile int *)0;
p = p; // to quiet "unused" warning
std::cout << "add_cv<int> == "
<< typeid(*p).name() << std::endl;
return (0);
}
add_cv_t<int> == int
